Jessica Matin will return to the senior line-up ahead of tomorrow's match against Collingwood.
The 19-year-old is the only change for Round 8, with Kate McCarthy (injured) withdrawn from the side following a stress response issue in her lower leg.
Matin's inclusion will see the Saints field seven players aged 20 or younger, with Best & Fairest Georgia Patrikios leading the way in terms of experience with 13 games.
Claudia Whitfort and Nadia von Bertouch have been named as emergencies.
St Kilda will look to claim its third win of the season over Collingwood on Saturday 20 March, with the opening bounce at Victoria Park pencilled in for 3:10pm.
IN: Matin
OUT: McCarthy (injured)
